**Angles and Energy by:**

Complementary angles are two angles that add up to 90 degrees

This is an example of a complementary angle

Triangles are a 3 sided polygon which angles add up to 180 degrees.

Supplementary angles are two angles that add up to 180 degrees.

This is an example of a supplementary angle

This is a triangle with angles that add up to 180 degrees.

**Kinetic Energy**

Potential Energy

Potential energy is energy that

is stored and has potential to move.

How to find a missing supplementary angle

110

x

First we have to know how much two supplementary angles add up to, which is 180 degrees. So you take 180 and subtract the given angle(110)from 180 and you should get 70 degrees.That means x=70 degrees.

x=70

To find out the missing angle of a triangle you first have to know how much all the angles add up to. In the first slide of triangles it says there is 180 degrees in a triangle. So first we need to add up the two angles given.

Kinetic energy is an object in motion

130+12= 157

________

23 degrees

x=23

This is how to find a missing angle in two complementary angles . Two complementary angles add up to 90 degrees.

65

x

All you have to do is subtrct the given angle from

90 degrees. So you do 90-65 which = 25

x=25
